vALvE Fen EXPLOSIVEEN'GINES.

To (177 10/1 0122 it m (11 con/cm Be it known that I. Annrnr J. RAY, a citizen of the United-States, residing at Fort Worth. in the county of Tart-ant and State of Texas. have invented certain new and useful lniprovements in Valves for Explosive-Engines, of which the following is a specification.

My invention relates to valves for explosive engines and to means for cooling the valve and to means for carbureting the explosive mixture, and the object is to provide a valve which has a conical or tapering surface so that the valve will be self grinding and self adjusting and which is internally air-cooled and to provide means whereby the ,mixt-ure of explosives will be doubly carbureted or mixed and purified and to provide an improved oiling system in the valvecasing.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference'is had to the accompanying drawings which form a part .of this application and specification.

Figure 1 is a side elevation of an engine whii'rh is equipped with the improvements hereinafter set forth. Fig. 2 is a broken sectional'view, showing the arrangement of the carbureting devices. Fig. 3 is a vertical section'of a valve in position in'its casing and showing the-CO11lleCtlOllOftllB casing with an engine cylinder. Fig. 4 is a side elevation of the valve. showing the intake and exhaust groove. Fig. 5 is a horizontal section of the valve and its casing, taken on the line of Fig. Fig. (3 is a vertical section of the valve, taken on the line y-g of Fig. 8. Fig. 7 is a vertical section of the valve. taken on the line z-z of Fig. 8. Fig. 8 is a plan view of the valve. Fig. 9 is a plan view of'the valve, showing a. varia-.

tion in the intake and exhaust groove, t-here being two grooves instead of one groove.

Similar characters of reference are used to indicate the same parts throughout the several views.

An engine cylinder 1 is shown provided with a spark plug 2-. valve casing 3 is formed preferably integral with cylinder 1 and this casing is provided with an intake port 4 and an exhaust port 5. The casing 3 is closed at the upper end by a plugG and mounted Specification of Letters Iatent. t t May 1 2 191 4 a Application filed February 27, 1912. Serial No. 680,352.

the casing is provided with radiating flanges 7 for cooling purposes. The casing-3 is taperingand a tapering or conical valve 8 in the casing. The casing 3 has a tapering seat 9 for the valve 8. 'The valve 8 has a stem 17 provided with a tapering portion 10 which engages the seat 9.

The valve 8 is a hollow valve, as shown in Figs. 5, 6, and 7,.and t-heopening in the valve extends through the stem so that the interior of the valve has communication with the atmosphere. The air circulates within the valve during operation and cools the valve constantly. The valve seats by gravity and a toggle joint or connection 11 is provided for drivingthe valve. The stemhas slots 12 by which the valve is engaged loosely by the toggle connection 11. The valve 8 has an intake and exhaust groove 13 which is tapered from the upper end downwardly and terminates at the seat 9. The groove 13 flared at the upper end at 1% so that the charge of explosive mixture will have an easy approach to the engine cylinder 1. The inner wall 15 and the entire inner surface of the valve will be cooled by air from the atmosphere. The stem has perforations 1G in part 17 thereof for taking in air and explosive mixture, as hereinafter explained. A pipe 18 takes the heated explosive mixture out of the valve constantly and in this way the valve is kept cool. A groove 19 is formed around the interior of the casing 3 for oiling the valve. The valve 8 being rotated in its seat 9, oil will be carried to all parts of the exterior surface and consequently to all parts of the interior surface of the casing 3. The location of the groove 19 is advantageous because the interior of the casing will be supplied with a thin film of oil and the oil will be rubbed on the exterior over the entire length thereof. The groove 13 will be no hindrance to the spreading of the oil because the centrifugal force will make the oil cling to the interior surface of the casing.

The variation shown in Fig. 9 consists in a valve having two exhaust and intake grooves 20 instead of one groove 13. The valve would have to be driven only one-half as fast as a valve having one groove.

The valve is rotated by gearing shown in Figs. 1 and 2. A stub or hollow shaft 21 is connected to the valve stem 17 bythe-toggle joint 11. A bearing 22 is provided for the stub or hollow shaft 21. The drawings showv m'ounted in the bottom of the mixing chamher, and has a flange which engages the ins1de of the bottom and a sleeve which pro-.

jects through the bottom, making thus an elongated bearing for the stub shaft 21. A worm gear wheel 26 is mounted rigidly on each shaft 21 and these gear wheels 26 are driven by gear wheels 27 which are rigidly mounted on a shaft 28 which is driven by any suitable gearing, as by gearing from the crank shaft (not shown). The return pipes 18 terminate in a secondary mixing chamber 29. Air and gasolene are introduced into the mixing chamber 524: through the orifice 30 and the quantity of gasolene introduced into chamber 24 is regulated by the needle valve- 31. Gasolene is contained in a tank 32 which has communication with the orifice 30 .through the neck 33 and the needle orifice 34. A float valve 35 of the ordinary type'in tank 32 regulates the height of gasolene in the adjustable needle orifice. The

amount of mixed air and gasolene is further controlled by the spring controlled gate v36 which is hingedly connectedat the upper edge of the orifice 30 and is adapted to swing I inwardly and outwardly about the projection 37 through which the gasolene is escaping. A bracket 38 is attached to the receiving nipple 39 and a rod &0 is pivotally connected to the gate 36 and exten ed through the bracket 38 and a spiral spring 41 is placed on the rod 40 between the bracket 33 and a nut 42 by which the tension Of the spring may be controlled to hold the gate 36 at diiierent posiqtions relative to the projection 37 for the purpose of increasing or decreasing the vacuum within the chamber. The amount of air and gasolene is controlled at the entry through the orifice 30 as it passes into the mixing chamber 2 1. The mixture passes throughthe perforations 16 up into the interior of the valve 8 where it is dried and is taken back through the pipe 18 into the secondary mixing chamber 29. The explosive mixture is fed from the tank 29 through the conduit or intake pipe43f A diluting valve a l; .for the secondary mixing chamber is provided for admission of air to the explosive mixture as the latter is passing to the rotary feed valves. The stem 15 projects out the casing and a spiral spring 16 is placc... on the stem l5 between the easing and the nut 17, and the amount of air admitted is controlled by the tension of the spring 16 for the purpose of increasing the vacuum, that is, for decreasing theinflow of intake.

air and increasing the inflow of gasolene at will, or for decreasing the vacuum, that is, increasing the inflow of air and decreasing the inflow of gasolene. The mixture of air and gasolene is carbureted partly in the mixing chamber 2 1 and partly within the valve itself. The rapid evaporation of gasolene in the valve 3, or the rapid absorption of 'gasolene by the air in the valve 8, has an intense cooling action aside from the atmospheric circulation. The cold temperature which is created in the operation of carbureters and which is usually lost in carbureters is utilized for cooling the valve.

The pipe 43 is provided with a butterfly or throttle-valve 48 which isprovided with a handle 49, and is used to control the amount of explosive mixture which is to be delivered to the intake port of the valve casing. The pipe 43-is connected to the intake manifold pipe 50 and port connections 51 connect pipe 50 to the valve casings 3. The port connections 51 connect the pipe 50 with the intake port 1 of each valve casing. Explosive mixtuiie escapes from the connection 51 through the intake port a into the groove 13 and from the valve casing through the port 52 into the engine cylinder 1. The exhaust pipe 53 is raised above the intake manifold and is to be connected to the exhaust ports 5 of the' valve casings 3 by port connections 54:. The casings 3 and cylinders 1 may be cooled 'in any suitable manner, while the valves are cooled by the circulation of explosive mixture, as heretofore explained.

The circulation shown in Figs. land 2' can be used to circulate either oil or water to cool the valves.

When the engine piston goes down on the intake stroke, a vacuum is created in the pipe 50, pipe 43, pipes 18, and consequently in the interior of valves 8. This will cause air and gas to pass through orifice 30 into the mixing chamber 2 1 and thence through perforations 16 into the interior of the valves 8. When gas passes through the intake port 5, it is received, in the grooves 13 in the valves which form parts of the combustion chambers and thence passes through the ports 52 which are always open or open all the time. The piston then returns on the compression stroke, the ports 5 being closed by the rotation of the valve. When the piston reaches the top center of its stroke, ignition takes place. The piston is thus started on the working or power stroke.

VVhen the piston reaches the bottom center Having fully described my invention,
